STAND DER TECHNIKSTATE OF THE ART
Eine der Ursachen für ein in einem Luftreifen erzeugtes Geräusch ist Kavitätsresonanzschall, welcher mit der Vibration der Luft, welche in den Reifen eingefüllt ist, einhergeht. Wenn ein Reifen abgerollt wird, wird die Luft innerhalb des Reifens durch die Vibration des Laufflächenabschnittes aufgrund von Unregelmäßigkeiten einer Straßenoberfläche in Vibration versetzt, welche den Kavitätsresonanzschall erzeugt.One of the causes of noise generated in a pneumatic tire is cavity resonance sound which accompanies the vibration of the air filled in the tire. When a tire is unrolled, the air inside the tire is vibrated by the vibration of the tread portion due to irregularities in a road surface which generates the cavity resonance sound.
Als ein Verfahren zum Reduzieren des Geräusches, welches durch das Phänomen der Kavitätsresonanz erzeugt wird, so wie es oben beschrieben wurde, wurde vorgeschlagen, dass ein Geräuschabsorptionselement in einem Kavitätsabschnitt angeordnet wird, welcher zwischen einem Reifen und einer Felge eines Rades ausgeformt ist (siehe zum Beispiel die

Eine Aufgabe der vorliegenden Erfindung ist es, einen Luftreifen bereitzustellen, in welchem das Anhaften (engl.: adhesion) eines Geräuschabsorptionselementes, welches aus einem porösen Material ausgeformt ist, verbessert wird und sie bezieht sich auch auf ein Verfahren des Herstellens des Luftreifens.An object of the present invention is to provide a pneumatic tire in which adhesion of a noise absorbing member formed of a porous material is improved, and it also relates to a method of manufacturing the pneumatic tire.
Diese Aufgabe wird durch den Luftreifen gemäß dem unabhängigen Anspruch 1 und das Verfahren gemäß dem unabhängigen Anspruch 8 gelöst. Die jeweiligen abhängigen Ansprüche definieren dabei bevorzugte Ausführungsformen.This object is achieved by the pneumatic tire according to independent claim 1 and the method according to
Ein Luftreifen gemäß der vorliegenden Erfindung zum Zwecke des Lösens der oben beschriebenen Aufgabe ist charakterisiert dadurch, dass er eine Harzlage (engl.: resin layer), ein Geräuschabsorptionselement und ein Verriegelungselement (engl.: locking element) umfasst. Die Harzlage ist entweder aus einem thermoplastischen Harz oder einer thermoplastischen Elastomermischung (engl.: thermoplastic elastomeric composition) geformt, welche durch das Dispergieren eines Elastomers in einem thermoplastischen Harz erhalten wird, und ist an zumindest einem Teil der inneren Oberfläche des Reifens ausgeformt. Das Geräuschabsorptionselement ist aus einem porösen Material ausgeformt und ist auf der Harzlage angeordnet. Das Verriegelungselement ist aus einem thermoplastischen Harz geformt und ist mit der Harzlage durch das Geräuschabsorptionselement hindurch mittels einer thermischen Verschmelzung (engl. thermal fusion) verbunden.A pneumatic tire according to the present invention for the purpose of achieving the above-described object is characterized in that it comprises a resin layer, a noise absorbing member, and a locking element. The resin layer is molded from either a thermoplastic resin or a thermoplastic elastomeric composition obtained by dispersing an elastomer in a thermoplastic resin, and is molded on at least a part of the inner surface of the tire. The sound absorbing member is formed of a porous material and is disposed on the resin sheet. The locking member is molded from a thermoplastic resin and is bonded to the resin layer through the noise absorbing member by means of thermal fusion.
Zusätzlich ist ein Verfahren zum Herstellen eines Luftreifens gemäß der vorliegenden Erfindung zum Zwecke des Lösens der oben beschriebenen Aufgabe charakterisiert durch das Umfassen der Schritte: Aushärten (engl.: curing) eines Luftreifens, der zumindest an einem Teil der inneren Oberfläche des Reifens eine Harzlage umfasst, welche entweder aus einem thermoplastischen Harz oder einer thermoplastischen Elastomermischung geformt ist, welche durch das Dispergieren eines Elastomers in einem thermoplastischen Harz erhalten wird, Anordnen eines Geräuschabsorptionselementes, welches aus einem porösen Material ausgeformt ist, auf der Harzlage, und Verbinden eines Verriegelungselementes, welches aus einem thermoplastischen Harz geformt ist, mit der Harzlage durch das Geräuschabsorptionselement hindurch mittels einer thermischen Verschmelzung.In addition, a method of manufacturing a pneumatic tire according to the present invention for the purpose of achieving the above-described object is characterized by comprising the steps of: curing a pneumatic tire comprising a resin ply on at least a part of the inner surface of the tire which is molded from either a thermoplastic resin or a thermoplastic elastomer mixture obtained by dispersing an elastomer in a thermoplastic resin, placing a sound absorbing member, which is formed from a porous material, on the resin sheet, and connecting a locking member made of a thermoplastic resin is molded with the resin sheet through the noise absorbing member by means of thermal fusion.
In der vorliegenden Erfindung ist, während die Harzlage umfassend ein thermoplastisches Harz als eine Matrix auf der inneren Oberfläche des Reifens ausgeformt ist, das Geräuschabsorptionselement an der Harzlage angeordnet, und das Verriegelungselement, welches aus einem thermoplastischen Harz geformt ist, ist mit der Harzlage durch das Geräuschabsorptionselement hindurch mittels einer thermischen Verschmelzung verbunden. Entsprechend ist es, selbst wenn das Geräusch absorbierende Element aus einem wärmehärtenden Harz (engl.: thermosetting resin), wie beispielsweise einem Polyurethanschaum, geformt ist, möglich, das Geräuschabsorptionselement an der inneren Oberfläche des Reifens fest zu fixieren. Die Fixierung durch die thermische Verschmelzungsbefestigung weist eine Klebekraft auf, die stärker ist als die einer Befestigung durch ein Gummiklebemittel oder ein Klebeband. Aus diesem Grund ist es möglich, den Verbindungszustand des aus dem porösen Material geformten Geräuschabsorptionselements vorteilhaft über eine lange Zeitperiode hinweg aufrecht zu erhalten. Als ein Resultat ist es möglich, einen Geräuschreduktionseffekt durch das Geräuschabsorptionselement über einen langen Zeitraum hinweg aufrechtzuerhalten.In the present invention, while the resin layer comprising a thermoplastic resin is molded as a matrix on the inner surface of the tire, the noise absorbing member is arranged on the resin layer, and the locking member which is molded of a thermoplastic resin is connected to the resin layer through the Sound absorption element connected through by means of a thermal fusion. Accordingly, even if the sound absorbing member is molded from a thermosetting resin such as polyurethane foam, it is possible to firmly fix the sound absorbing member to the inner surface of the tire. The fixation by the thermal fusion fixing has an adhesive force stronger than that of fixing by a rubber adhesive or an adhesive tape. For this reason, it is possible to advantageously maintain the connected state of the sound absorbing member formed of the porous material for a long period of time. As a result, it is possible to maintain a noise reducing effect by the noise absorbing member over a long period of time.
Es ist bevorzugt, dass das konstituierende Material (engl.: constituent material) des Verriegelungselementes von der gleichen Sorte eines thermoplastischen Harzes ist, wie das, welches in der Harzlage umfasst ist. Der Unterschied zwischen der Verschmelzungstemperatur (engl. fusing temperature) des Verriegelungselementes und der Verschmelzungstemperatur der Harzlage soll nicht mehr als 20°C sein. Wenn sich die Verschmelzungstemperaturen einander annähern, wird das thermische Verschmelzungsverbinden erleichtert. Zusätzlich ist es bevorzugt, dass das poröse Material des Geräuschabsorptionselements ein Polyurethanschaum ist. Um genauer zu sein ist, da der Polyurethanschaum eine bevorzugte Geräuschabsorptionscharakteristik zeigt, der Polyurethanschaum geeignet als das konstituierende Material für das Geräuschabsorptionselement.It is preferred that the constituent material of the locking member be of the same kind of thermoplastic resin as that included in the resin layer. The difference between the fusing temperature of the locking element and the fusing temperature of the resin layer should not be more than 20 ° C. When the fusing temperatures approach each other, thermal fusion bonding is facilitated. In addition, it is preferable that the porous material of the sound absorbing member is a polyurethane foam. To be more specific, since the polyurethane foam exhibits preferable sound absorption characteristics, the polyurethane foam is suitable as the constituent material for the sound absorption member.
In dem Luftreifen gemäß der vorliegenden Erfindung kann die Harzlage auf einem Teil der inneren Oberfläche des Reifens als Basis zum Anbringen des Geräuschabsorptionselementes an der inneren Oberfläche des Reifens ausgeformt sein. Zum Zwecke des effektiven Verwendens des Materials ist es jedoch bevorzugt, dass die Harzlage auf der gesamten Region der inneren Oberfläche des Reifens als eine Lage zur Verhinderung des Luftdurchlasses (engl.: air permeation preventive layer) ausgeformt ist. Zusätzlich ist es vorteilhaft, wenn ein Abschnitt, in dem das Verriegelungselement und die Harzlage miteinander durch die thermische Verschmelzung verbunden sind, in einem Intervall in der Reifenumfangsrichtung angeordnet sind und auch dass das Verhältnis zwischen dem Intervall H und der Breite W des Geräuschabsorptionselementes 0,2W ≤ H ≤ 4W ist. Entsprechend ist es möglich, eine bevorzugte Haltbarkeit bei minimaler Verarbeitung sicherzustellen.In the pneumatic tire according to the present invention, the resin layer may be formed on a part of the inner surface of the tire as a base for attaching the noise absorbing member to the inner surface of the tire. However, for the purpose of effectively using the material, it is preferable that the resin layer is formed on the entire region of the inner surface of the tire as an air permeation preventive layer. In addition, it is preferable that a portion where the locking member and the resin layer are bonded to each other by the thermal fusion are arranged at an interval in the tire circumferential direction and also that the ratio between the interval H and the width W of the noise absorbing member is 0.2W ≤ H ≤ 4W. Accordingly, it is possible to ensure preferable durability with minimal processing.
Bei dem Verfahren des Herstellens eines Luftreifens gemäß der vorliegenden Erfindung ist es vorteilhaft, wenn ein Ultraschallschweißgerät für das thermische Verschweißungsverbinden des Verriegelungselementes mit der Harzlage verwendet wird. Wenn ein solcher Ultraschallschweißer verwendet wird, ist es möglich, das Verriegelungselement und die Harzlage lokal zu erhitzen. Entsprechend ist es möglich, eine exzellente Balance zwischen der Verarbeitbarkeit und der Haltbarkeit zu erreichen. Zusätzlich ist es, wenn ein Oszillationshorn (engl.: osciallating horn), welches angefaste Endabschnitte der Spitze in deren Breitenrichtung aufweist, als ein Oszillationshorn für den Ultraschallschweißer verwendet wird, möglich, das Auftreten eines Weißungsphänomens (engl. whitening phenomenon) im Verriegelungselement zu unterdrücken. Als ein Resultat kann die Haltbarkeit weiter verbessert werden.In the method of manufacturing a pneumatic tire according to the present invention, it is advantageous that an ultrasonic welder is used for thermally weld-bonding the locking member to the resin sheet. When such an ultrasonic welder is used, it is possible to locally heat the locking element and the resin layer. Accordingly, it is possible to achieve an excellent balance between workability and durability. In addition, if an oscillation horn having chamfered end portions of the tip in the width direction thereof is used as an oscillation horn for the ultrasonic welder, it is possible to suppress the occurrence of a whitening phenomenon in the locking member . As a result, the durability can be further improved.

Die thermoplastische Elastomerzusammensetzung wird erhalten durch das Schmelzen und Kneten des thermoplastischen Harzes und des Elastomers (wenn ein Gummi verwendet wird, ist das Gummi ein unvulkanisiertes) im Vorlauf unter Verwendung eines zwei-Schrauben-Knet-Extrudes oder ähnlichem und dann durch das Dispergieren der elastomeren Komponente in dem thermoplastischen Harz unter Formung einer kontinuierlichen Phase. In einem Fall, in dem die elastomere Komponente vulkanisiert werden soll, kann das Elastomer dynamisch vulkanisiert werden durch das Hinzufügen eines Vulkanisierungsmittels während des Knetens. Zusätzlich können die unterschiedlichen Additionsmittel (außer dem Vulkanisierungsmittel) zu dem thermoplastischen Harz oder der elastomeren Komponente während des Knetens hinzugefügt werden, aber bevorzugt mit dem thermoplastischen Harz oder der elastomeren Komponente im Vorlauf vor dem Kneten bevorzugt gemischt werden. Eine Knetmaschine, welche zum Kneten des thermoplastischen Harzes und des Elastomers verwendet wird, ist nicht besonders eingeschränkt und ein Schraubenextruder, ein Kneter, ein Banbury-Mixer, ein zwei-Schrauben-Knetextruder oder ähnliches kann verwendet werden. Unter diesen ist es bevorzugt, dass der zwei-Schrauben-Knetextruder zum Kneten der Harzkomponente und der Gummikomponente und für das dynamische Vulkanisieren der Gummikomponente verwendet wird. Zusätzlich ist es ebenso möglich, zwei oder mehrere Arten von Knetmaschinen zu verwenden und dann das Kneten nacheinander durchzuführen. Als Bedingung für das Schmelzen und Kneten sollte die Temperatur nicht weniger sein als die, bei welcher das thermoplastische Harz geschmolzen wird. Zusätzlich ist das Scherverhältnis zum Zeitpunkt des Knetens bevorzugt 2500 bis 7500 sec-1. Die gesamte Zeitdauer für das Kneten ist bevorzugt 30 Sekunden bis 10 Minuten. Wenn das Vulkanisierungsmittel hinzugefügt ist, ist die Zeitdauer für die Vulkanisierung nach dem Hinzufügen des Vulkanisierungsmittels bevorzugt 15 Sekunden bis 5 Minuten. Die thermoplastische Elastomerzusammensetzung, die durch das oben beschriebene Verfahren hergestellt wird, wird durch Extrusion unter Verwendung eines Harzextruders oder durch Kalandern in einen Film geformt. Als das Verfahren des Formens der thermoplastischen Elastomerzusammensetzung in einen Film kann ein allgemeines Verfahren des Formens eines thermoplastischen Harzes oder eines thermoplastischen Elastomers in einen Film verwendet werden.The thermoplastic elastomer composition is obtained by melting and kneading the thermoplastic resin and the elastomer (when a rubber is used, the rubber is an unvulcanized one) in advance using a two-screw kneading extruder or the like, and then dispersing the elastomer Component in the thermoplastic resin to form a continuous phase. In a case where the elastomeric component is to be vulcanized, the elastomer can be dynamically vulcanized by adding a vulcanizing agent during kneading. In addition, the various addition agents (other than the vulcanizing agent) may be added to the thermoplastic resin or the elastomeric component during kneading, but preferably mixed with the thermoplastic resin or the elastomeric component in advance of the kneading. A kneading machine used for kneading the thermoplastic resin and the elastomer is not particularly limited, and a screw extruder, a kneader, a Banbury mixer, a two-screw kneading extruder or the like can be used. Among them, it is preferable that the two-screw kneading extruder is used for kneading the resin component and the rubber component and for dynamically vulcanizing the rubber component. In addition, it is also possible to use two or more kinds of kneading machines and then to perform kneading one after another. As a condition for melting and kneading, the temperature should not be lower than that at which the thermoplastic resin is melted. In addition, the shear ratio at the time of kneading is preferably 2500 to 7500 sec -1 . The total time for kneading is preferably 30 seconds to 10 minutes. When the vulcanizing agent is added, the time for vulcanization after the vulcanizing agent is added is preferably 15 seconds to 5 minutes. The thermoplastic elastomer composition produced by the method described above is formed into a film by extrusion using a resin extruder or by calendering. As the method of molding the thermoplastic elastomer composition into a film, a general method of molding a thermoplastic resin or a thermoplastic elastomer into a film can be used.

BeispieleExamples
Luftreifen eines herkömmlichen Beispiels und der Beispiele 1 und 2 (Reifengröße: 215/55R16) wurden hergestellt. In dem Luftreifen des herkömmlichen Beispiels wurde ein Geräuschabsorptionselement, welches aus einem bandförmigen Urethanschaum (einer Breite von 150 mm bei einer Dicke von 20 mm) an der inneren Oberfläche des Laufflächenabschnittes über den gesamten Umfang des Reifens hinweg unter Verwendung eines Gummiklebemittels befestigt. Andererseits wurden in jedem der Luftreifen der Beispiele 1 und 2, während eine Harzlage, welche aus einer thermoplastischen Elastomerzusammensetzung geformt war, in dem gesamten Bereich der inneren Oberfläche des Reifens geformt war, ein Geräuschabsorptionselement, welches aus einem bandförmigen Urethanschaum (einer Breite von 150 mm bei einer Dicke von 20 mm) auf der Harzlage angeordnet war, auf der inneren Seite des Laufflächenabschnittes entlang dem gesamten Umfang des Reifens angeordnet. Dann wurden Verriegelungschips in Intervallen von ungefähr 200 mm jeweils an dem Geräuschabsorptionselement entlang der Reifenumfangsrichtung angeordnet. Die Verriegelungschips wurden dann mit der Harzlage durch thermisches Verschmelzen unter Verwendung des Ultraschallschweißers befestigt. Es sollte beachtet werden, dass der Unterschied zwischen der Verschmelztemperatur des Verriegelungselementes und der Verschmelztemperatur der Harzlage im Beispiel 1 bei nahezu 30°C festgelegt war, während der Unterschied zwischen der Verschmelztemperatur des Verriegelungselementes und der Verschmelztemperatur der Harzlage auf nahezu 5°C in Beispiel 2 festgelegt war.Pneumatic tires of Conventional Example and Examples 1 and 2 (tire size: 215 / 55R16) were manufactured. In the pneumatic tire of the conventional example, a noise absorbing member made of a tape-shaped urethane foam (a width of 150 mm by a thickness of 20 mm) was attached to the inner surface of the tread portion over the entire circumference of the tire using a rubber adhesive. On the other hand, in each of the pneumatic tires of Examples 1 and 2, while a resin sheet molded from a thermoplastic elastomer composition was molded in the entire area of the inner surface of the tire, a noise absorbing member made of a tape-shaped urethane foam (a width of 150 mm at a thickness of 20 mm) was arranged on the resin layer, arranged on the inner side of the tread portion along the entire circumference of the tire. Then, locking chips were arranged at intervals of about 200 mm each on the noise absorbing member along the tire circumferential direction. The locking chips were then attached to the resin sheet by thermal fusing using the ultrasonic welder. It should be noted that the difference between the fusing temperature of the locking element and the fusing temperature of the resin layer in Example 1 was set at almost 30 ° C, while the difference between the fusing temperature of the locking element and the fusing temperature of the resin layer was set at almost 5 ° C in Example 2 was set.
Ein Fahrtest wurde durchgeführt an jedem der Luftreifen des herkömmlichen Beispiels und der Beispiele 1 und 2 unter Verwendung einer Trommeltestmaschine unter den Bedingungen eines inneren Druckes von 150 kPa und einer Geschwindigkeit von 80 km/h, so dass die Strecke, über die der Reifen fuhr bis das Geräuschabsorptionselement abgelöst wurde, gemessen wurde. Die Resultate der Tests sind in Tabelle 1 gezeigt. Die Bewertungsresultate sind durch Indizes angedeutet, in dem das Bewertungsresultat des herkömmlichen Beispiels als 100 genommen wurde. Je größer der Index ist, desto bevorzugter ist die Haltbarkeit des Reifens.
Tabelle 1
Wie es aus der Tabelle 1 klar wird, haben jeder der Luftreifen der Beispiele 1 und 2 eine verbesserte Haltbarkeit gezeigt, verglichen mit dem Luftreifen des herkömmlichen Beispiels. Die Verbesserung in der Haltbarkeit war außergewöhnlich insbesondere bei Beispiel 2.As is clear from Table 1, each of the pneumatic tires of Examples 1 and 2 exhibited improved durability as compared with the pneumatic tire of the conventional example. The improvement in durability was exceptional especially in Example 2.
